Description: PR-1 is a water-based resin, used to promote adhesion on problematic unfinished leathers such as stain-treated anilines, pull-ups, or oil-tans, and semi-aniline (very lightly coated) leather. It is also appropriate for areas of finished leather where the topical finish is worn away, seriously compromised, or pH damaged. It is a solvent-tolerant soft resin that is able to penetrate the fiber structure and provide a good base for adhesion of colors or fillers.
Application: PR-1 should be reduced 1:3 with denatured alcohol. HDPE or PET plastic bottles are recommended.
The primer mixture can be applied with a sponge, foam block, or cotton rag in an over-lapping circular motion. It can also be used in conjunction with a mild abrasive pad or exfoliating glove to drive the primer through UV- or pH-damaged surface fibers into the intact, underlying fiber structure.
Solvent handling and application procedures should be observed while applying the primer mixture (proper ventilation, respiratory protection, gloves, etc.).
The primer does not have an extended cure time. Once the solvent has evaporated, the area where the primer has been applied can have filler or colors applied immediately.
